at 848 pm edt, doppler radar indicated strong Thunderstorms, capable of producing winds to up 30 knots. These Thunderstorms were located along a line extending from 16 nm west of lake erie metropark harbor to 8 nm northwest of Monroe harbor to near luna pier, moving northeast at 20 knots.
strong Thunderstorms will be near, Monroe harbor, bolles harbor of refuge, north cape, luna pier, woodland beach, and detroit beach around 855 pm edt. Stony point around 900 pm edt. Lake erie metropark harbor, estral beach, and gibraltar around 910 pm edt. Detroit river light around 915 pm edt. Elizabeth park marina and wyandotte around 920 pm edt. Grosse ile around 925 pm edt.
other locations impacted by strong Thunderstorms include woodland beach, stony point, gibraltar, estral beach, and detroit beach.
precautionary/preparedness actions - .
mariners can expect gusty winds up to 30 knots, locally higher waves, and lightning strikes. Boaters should seek safe harbor immediately until these storms pass.
these strong Thunderstorms will likely produce winds up to 30 knots, and could pose a serious hazard for boaters. A special marine warning may eventually be required when these storms reach the nearshore waters. Boaters should consider heading for shore before these storms arrive.

KEY MESSAGES
- Cooler, drier weather continues through Thursday.
- Temperatures return to around or slightly above average Friday into early next week.
- Next chances for rain look to arrive Saturday.
AVIATION
The plume of clouds which streamed across Se Mi overnight are now exiting to the east. Recent satellite data is showing some additional clouds developing off southern Lake Michigan. In light of the ambient dry air, the expectation is for these to generally erode with the onset of daytime heating late this morning. This will leave generally clear skies today. Daytime growth of the mixed layer will result in a modest uptick in the WSW winds as 15 to 20 knot winds will be in the mixed layer.

DISCUSSION...
SE MI remains on the southern fringe of an arctic airmass as upper troughing holds across the central Great Lakes. While the airmass is thermally unchanged from Wednesday, 850mb temps holding around -7C, last remnants of low level moisture from the system earlier this week were stripped out by last evening (28.00Z KDTX RAOB sounding had PW of 0.17"). This in combination with continuing subsidence from broad surface high pressure over the Mississippi river valley leads to mostly sunny to sunny skies today with any cloud coverage confined to passing cirrus. Ample insolation is still expected to overcome the colder start with forecast highs in the upper 40s to around 50 for the southern half of the region. Northern areas more favored towards mid 40s owing to closer proximity to the core of the airmass.
Low amplitude ridging currently over the Plains eventually builds into the Great Lakes Friday shunting troughing to the Northeast.
Given more zonal nature of the ridge, WAA into southern lower MI won't be particularly strong, though still sufficient to bring 850mb temps back into the low/mid positive single digits (C)- which are a few degrees above normal for late March (average is around 0C). With clear skies still likely in place, Friday's highs push into the 50s for nearly all of the area, save for the Thumb, with southern areas having potential to reach well into the mid 50s.
Midlevel shortwave riding along the ridge is set to reach the southern Great Lakes/Ohio Valley early Saturday. While certain aspects of this system are in good model agreement: narrow ribbon of stronger isentropic ascent supported overall by a ribbon of Gulf moisture pulled north along the Mississippi; exact track and broadness of the circulation still carry a fair amount of uncertainty. Trends have favored a slightly more diffuse parent PV anomaly resulting in a broader region of weak ascent/light precip- offering rain chances for the majority of SE MI daytime Saturday.
However, the surface low track has trended further over IN/OH which, should these outcomes hold, would keep the best isentropic ascent and subsequent higher rainfall amounts likewise south of the state line. While still a moving target, latest NBM looks reasonable based on current solution space with PoPs lowered to chance (40-50%) for all SE MI outside of areas near the state border which still carry likelies (~60%).
System vacates the region overnight Saturday allowing for a drier, still mild, finish to the weekend Sunday. Active pattern looks to make a return Monday into Tuesday as the lingering baroclinic zone draped across the Midwest and Ohio Valley/southern Great Lakes activates in response to a potent Pacific mid-upper trough ejecting out of the Intermountain West into the Plains.
MARINE...
High pressure builds in across the southern and western Great Lakes today which maintains a southwest wind direction across the central Lakes. Wind speeds will be mainly around 10 to 15 knots but the southwest fetch down Saginaw Bay will produce locally higher winds up to around 20 knots there. The high pressure maintains control through the late week until the next low pressure moves through on Saturday, bringing rain and snow to parts of the region. At this time winds look to stay below marine headline criteria, but a shift to more of a northerly direction will likely accompany the system.
